GIS Lookup: Detailed Data Layer Listing

Data Layer GraphicTitle: "World WorldSat Color Shaded Relief" (2006)
Description: World WorldSat Color Shaded Relief represents a cloud-free view of the Earth produced by mosaicking hundreds of individual 1996 NOAA weather satellite images. These satellites orbit the Earth at an altitude of 800 km (520 miles). The image has a cell size of 2 kilometers (at the equator). On completion of the base satellite mosaic, the land areas were enhanced with shaded relief imagery, derived from 1,000-meter digital elevation data, bringing the Earth's topography to life. For the Ocean areas, WorldSat incorporated ocean floor relief data (bathymetry), providing a view of the undersea topography. World WorldSat Color Shaded Relief provides a shaded relief background on which other data can be displayed.
